摘要
介绍一种只需要一个偏置控制端口 ,采用正负脉冲驱动的 T形结鳍线单刀双掷开关的设计方法 .在电路中采取改进措施 ,提高了隔离度、降低了插入损耗 .测量结果表明 ,开关在 Ka频段内 ,插入损耗≤ 1.5 d B,隔离度≥30 d B;在 W频段内 ,插入损耗≤ 2 d B,隔离度≥ 2 5 d
The design method, manufacture and testing results of new kind of T junction finline single pole double throw (SPDT) switch, which has only a controlling port with positive or negative pulses, was given. In order to increase the isolation and reduce the insert loss of the switch, some improving measures were taken in the circuit. The test results show that the insert loss less than or equal to1.5dB and the isolation greater than or equal to 30dB in Ka bands and the insert loss less than or equal to 2dB and the isolation greater than or equal to 25dB in W hands.
